Thin water sail boats suggestions. Some days the sandy mud bottom of river by our dock is close to the top of water. Mostly 3to 5 foot but 1 or2 times a year wind blows water out .want sail boat that can set on bottom if I'm not their to anchor out in deep water. More I study more I seem to read information biased dy what they owne.ok 22-24 ft swing keel but some swing up flush with bottom some swing up into keel box 1 to 1.5 out bottom the 1st might set better in bottom 2 nd style more room inside. Any suggestions average deepth of river6-8ft want to week end sail The Albamarle sound over nights boat will stay at dock during season pulled out in winter won't be hauling boat around .launch and set up once a year
